The LV8105W is a predriver IC designed for variable speed control of 3-phase brushless motors. It can be used to implement a high- and low-side output N-channel power FET drive circuit using a built-in charge pump circuit. High-efficiency drive is possible through the use of low noise PWM drive and synchronous rectifying systems.
